Destiny 2 HONEYDEW error code - How to fix
The HONEYDEW error code happens, according to Bungie, when "public access to an activity has been overridden. This happens when servers go down or when certain issues have been found."
Bad news, there's nothing you can do on your end to fix it, as it's all up to Bungie to come up with a solution. The good news is, the devs have acknowledged the situation and are actively working on solving it.
